The Air Force is investigating the connection between the failure of its classified network, dubbed SIPRNet, at Creech Air Force Base and a series of high-profile airstrikes that went terribly wrong in September this year.

Creech Air Force Base is a secret facility outside Las Vegas, where military and Air Force pilots sitting in dark and air-conditioned rooms, 7100 miles from Syria and Afghanistan, remotely control their "targeted killing" drone campaign in a video-game-style warfare.

From this ground zero, Air Force pilots fire missiles just by triggering a joystick on a targeted areas half a world away, as well as operate drones for surveillance and intelligence gathering.

Drone operation facility at Creech Air Force Base -- a key base for worldwide drone and targeted killing operations -- has been assigned as ‘Special Access Programs’, to access SIPRnet.

What is SIPRnet?

SIPRNet, or Secret Internet Protocol Router Network, is a global United States military Internet system used for transmitting classified information, intelligence, targets, and messages at the secret level.

In other words, SIPRNet is completely parallel Internet, uses the same communications procedures and has been kept separate from the ordinary civilian Internet.

Approximately 3 Million people with secret clearances have access to SIPRNet, which includes Pentagon and military officials, Intelligence agencies, FBI, as well as diplomats in US embassies all around the World.

Classified Network Crashed at Creech Base

The network at Creech Air Force Base was crashed in early September that impacted "critical services," and has not been completely rebuilt, according to US government contracting records.

"On 9 September 2016, the SIPRNet system currently in operation at Creech AFB failed, and critical services were impacted," reads a contracting notice posted by the US government in early October.

"The services were somewhat restored with the use of multiple less powerful devices. This temporary solution stabilized the services, but will not be able to maintain the demand for very long. If this solution fails, there is currently no other backup system."

The officials would not say whether the failure was due to internal technical faults, a cyber attack, or a state-sponsored hacker. They would also not say if JWICS — a separate internet system that handles top-secret information — at Creech was also affected.

US Drones Killed around 100 Innocents within Two Weeks

Within weeks of the computer disaster, a series of airstrikes went terribly wrong, which resulted in scores of deaths in Syria, Afghanistan, and Somalia, according to BuzzFeed News.

On September 17, 62 Syrian soldiers were accidentally killed by US airstrikes in the middle of a ceasefire. On September 28, 15 innocent civilians were reportedly killed in Afghanistan by a US drone, as well as 22 Somali soldiers were reportedly killed in Somalia by US drone strikes.

All the cases are under review and investigation, and there has been no official explanation for targeting innocent people, though the United States expressed its regrets quickly after the incident, according to reports.

On October 7, the Air Force quietly announced that Creech base would be subject to a surprise cyber security inspection and warned personnel to be wary of phishing attacks and to be extra careful in securing their login credentials.

Has U.S. Classified Network Been Hacked?

These classified networks are definitely not connected to the Internet, but this does not mean that malware or well-resourced hackers can never found their ways into these critical networks.

If confirmed, this would not be the first time, when a classified computer network of US military has been compromised.

In the year 2008, The Pentagon acknowledged a significant cyber attack, Operation Buckshot Yankee, where a foreign intelligence agent used a USB drive to infect military computers used by the Central Command in overseeing combat zones in Iraq and Afghanistan with a specially crafted malware.

You might be aware of Chelsea Manning (then known as Bradley Manning), an army soldier who made headlines in 2013 when she was sentenced to 35 years in prison for leaking over 700,000 classified files to WikiLeaks.

Manning allegedly downloaded those secret documents from SIPRNet using a Lady Gaga CD.

Since these classified networks have a significant role in US national security, terrorist groups and state-sponsored hackers belonging to sophisticated nation-states like China, Russia, Iran, and North Korea have always shown large interest in targeting them.

"Sujan was an external operations planner and a United Kingdom-educated computer systems engineer. Sujan supported ISIS hacking efforts, anti-surveillance technology and weapons development. Now that he is dead, ISIL has lost a key link between networks."

The 31-year-old man not just suspected of running a global money-laundering ring for ISIS from his former base in Britain, but also believed to have paid for a 15-year-old British girl to travel to become a jihadi bride, The Mail reported.

Sujan came to the UK as a student in 2003, where he studied computer system engineering at the University of Glamorgan.

After finishing his studies, Sujan settled in Cardiff and brought his wife Shayma Akter, 28, in 2005. Then in 2006, he founded an IT firm 'Ibacs' with his brother in Newport, near Cardiff. But due to failing in receiving a visa extension to remain in the UK, he was forced to leave the country in 2014.

Before leaving the United Kingdom, Sujan told his friends that he and his wife wanted to return to his native country of Bangladesh.

However, Sujan made to join ISIS and soon became a senior figure for the terror group after replacing another top hacker from the UK, Junaid Hussain, who was killed by an air strike in August.

The US drone strike that blasted Sujan in Syria was part of a wider strategic bombing raid that took place over a number of days and killed ten ISIS leaders including Sujan.

But something has emerged what we don't know about the death of Hussain.

The infamous hacker who in the past hacked the Anonymous pseudo-official Twitter accounts, now claims he served as an FBI informant to help the US government track down Junaid Hussain.

The hacker, goes by the online alias Shm00p (@5hm00p), is a member of the hacking collective Rustle League and believes he is "99.9% sure" that the information given by him to the FBI agents led to the extrajudicial killing of Hussain.

"What the fuck have I done," Shm00p tweeted early Sunday morning.

Over 15 hours later after his first tweet, Shm00p made a series of tweets at the FBI Twitter account.

"I lost a lot of good friendship and my fucking honor," Shm00p tweeted at the FBI. You can see an archived copy of his now deleted tweets here. "I am so embarrassed to show my face in public now because of this," he continued.

ISIS hackers have hacked tens of thousands of Twitter accounts, including the accounts of the members of CIA and the FBI, in revenge for the US drone strike that killed a British ISIS extremist in August.

The Cyber Caliphate, a hackers group set up by British ISIS member Junaid Hussain, urged its supporters and followers to hack Twitter accounts in order to take revenge of Husain's death.

Over 54,000 Twitter Accounts Hacked!

As a result, the hackers were able to hack more than 54,000 Twitter accounts. Most of the victims targeted by Jihadis appear to be based in Saudi Arabia though some of the them are British.

One of the victims based in Saudi Arabia, whose Twitter account was compromised by the ISIS extremists, said, "I am horrified at how they got hold of my details."

The extremists not only hacked thousands of Twitter accounts, but they also posted hacked personal information, including phone numbers and passwords, of the heads of:

The Central Intelligence Agency (CIA)

The Federal Bureau of Investigation (FBI)

The United States's National Security Agency

'We Are Back with a BANG'

Hussain was a British hacker who rose to prominence within Islamic State Terrorist group (better known as ISIS) in Syria as a top cyber expert to mastermind the ISIS online war before a US drone killed him in August.

After Hussain's death, Cyber Caliphate (@cyber_caliph), which took control of the official Twitter and YouTube accounts of the US military's Central Command (CENTCOM) in January, reappeared on Twitter last Sunday.

"We are back," Cyber Caliphate declared in an opening tweet.

Before its accounts got suspended by Twitter, Cyber Caliphate tweeted a link to the database that contained stolen Twitter accounts, including passwords, although the data could not be verified yet.

The incident came just a day after another hacking group, Crackas With Attitude (CWA), claimed to have gained access to a Law Enforcement Portal that contains arrest records and tools for sharing information about terrorist events and active shooters.

The hackers group that was active in 2012, and was known for gaining access to the former Prime Minister Tony Blair's address book and then publishing information from it.

The British hacker who actually obtained the Prime Minister's address book and was jailed for six months in 2012, named Junaid Hussain, has been killed in a United States drone strike in Syria, a source familiar with the matter said on Wednesday.

Hussain was a British hacker who rose to prominence within Islamic State group in Syria as a top cyber expert to mastermind the ISIS online war.

The U.S. military conducted the operation; no involvement of the British government in the killing of Hussain, a British citizen from Birmingham.

Junaid Hussain Killed in Raqqa

Hussain was killed in Raqqa, located in northern Syria, which has been treated as a safe place by ISIS.

The United States has yet to officially announce Hussain's death, which is not verified by the officials, beyond saying that the country launched airstrikes against ISIS on Tuesday near Raqqa.

"We have a high level of confidence [Hussain] was killed," one of the U.S. officials told CNN Wednesday.

The U.S. officials believe that the 21-year-old Hussain was heavily involved in inspiring attacks and was their high-value target in ISIS.

Hussain was involved in the Garland, Texas, cartoon contest attacks and helping ISIS in obtaining the passwords of the US Central Command's Twitter and YouTube accounts to send pro-Isis messages.

The officials believe that the drone strike on Hussain's vehicle Tuesday was a great "intelligence success."

Hussain's death was the second airstrike conducted against ISIS leaders and militants. Last week's airstrike killed one of the senior ISIS members, Hajji Mutazz, in Iraq.

Chinese smartphone maker OnePlus who recently announced that the company is planning to launch its latest flying drone, OnePlus DR-1, saying it would be a "Game Changer."

There have already been some speculations about a drone from OnePlus circulating on the Internet, but now the company has confirmed during a Reddit AMA (Ask Me Almost Anything) session that OnePlus DR-1 (aka DR-ONE) will land on its online store next month.

OnePlus also posted a Vine video on Tuesday with the caption "Feeling adventurous? The DR-1 is flying to our store next month. #OneGameChanger." The six-second short video did not give much information about the new drone, but it hints more or less that the company is working on a drone.

The product page of DR-1 sectioned impressive lines such as "innovating a whole new way of thinking about drones" and telling users to "experience the next age of aviation technology with effortless transportation and storage" with this tiny 70mm-wide flying machine.

You may have caught by now that OnePlus DR-1 is an April Fools' day prank, but the company has turned its prank into pretty much reality by actually selling the tiny quad-copters, which will be available in limited quantity for just $20 (about AU$25 or £15).

HA! The so-called game changer actually came out to be a tiny quadcopter, which is about half the size of the OnePlus One.

SPECIFICATIONS OF ONEPLUS DR-1

Flight time of 7 to 8 minutes

Needs a recharge for 20 minutes between flights

Weight of just 12.5 grams

Frame size of about 70mm (2.75-inch)

DR-1 is a red-colored plastic chassis with four blades and features ultra-bright orientation LEDs. It fits in the palm of your hand and comes with an Infrared (IR) remote controller that has dual flight mode settings. So, it seems like you’ll not be able to use your phone to pilot DR-1, the controller is used to do so.

So if you act fast, there is a chance for you to grab one from the company's website, which will be shipped only to a US address.
